System Crash with Dual Boot Configuration on HDD1 (Windows 10) and HDD2" (Kubuntu 18.04)

[JA5AEA]

I purchased a i7-8700 with a single HDD configured HP Pavilion desktop at the beginning of this year. Then, I attached my owned SSD drive on HDD1 SATA connector and installed Kubuntu 18.04 with dual boot.  After this system change, I face a few system crash occasion every day. A majority situation  of system crash is to access HDDs to open files with file explore. When I reboot the machine, I see CMOS parity error indication but it came back to normal operation with "enter" from the keyboard.

HP suggested to replace the machine to new one and I agrred the replacement  but I can see the same issues with the replaced machine.  So far, I see the following symptom to create the issues.

1. System crash would not occur if BIOS is set to  be disabled from UEFI Boot candidates at F10. At this moment, this is the smart way to select two OS at the power up.

2. System crash would not also occur either HDD1 or HDD2 SATA connector  is disconnected before power up. This is ugly way but it can safely select OS.

3. System crash would not occur if two OSs are installed to single HDD i.e. HP provided  original HDD1.

4. I checked UEFI boot configuration with bcedit and EFI system configuration with diskpart and it seems to be fine.

I have never seen this type of system crash in the  previous HP Pavilion with two HDD dual boot configuration for a couple of years and I am wondering the cause of the problem.

Any suggestion to solver the issue?

I'm sorry, but we here are not equipped to provide detailed Linux support.

HP only warranties their PCs for usage with the OS that comes preinstalled. IF you replace that with Linux, or add a Linux OS, then you assume full responsibility for maintaining that -- as HP provides Linux assistance only on Redhat and then only to commercial customers.

Any hardware that does not work will then range from simple (if there are Linux drivers available) to impossible (if there are NO Linux drivers available) to fix.

Since HP does not provide Linux drivers, your best bet for Linux support is to contact the support forum for the Linux distro you are using.

Folks on Linux support forums have experience using a variety of machines with Linux and know a lot about driver and installation issues. You will be able to get sound and detailed help there.

Good Luck

My system became stable even with dual boot configuration by disabling HP secure boot. I do not understand why this HP machine crashes at the disk access timing quite a long time past after secure booting. 

I am happy three  month nighmare was gone and Kubuntu smoothly works with my two HP machines. 

WAWood, thank you very much for advice.

"HP Support Assistant" software provided two updates which I believe relatets to my problems and I run my machine flawlessly with dual boot configuration along with HP UEFI secure boot on.

1. HP Consumer Desktop PC BIOS Update (ROM Family SSID 843B) installed on April 24

2. HP PC Hardware Diagonistics UEFI installed on April 25

"Note on item "  says it adds "4ms debouce time workaround for PSU..." and therefore I believe HP knows the cause of my PC  problem even though customer service has not yet contacted me personally.
